Effect of soil structure breakdown on splash erosion in different soil textures
This study was carried out to investigate the role of soil structure in splash erosion in semi-arid soils. Splash erosion was measured in four soil textures (silty clay loam, sandy clay loam, silt loam and sandy loam) with two soil structure conditions (with natural structure and under aggregate breakdown) using a simulated rainfall with 50 mmh-1 in intensity for 30 min in splash caps with 10-c...
متن کاملCalibration and evaluation of water infiltration models in different soil textures
Accurate estimation of water infiltration into the soil is important for the design of irrigation systems. Therefore, calibration of different models is necessary to estimate the permeability in different regions. The aim of the present study was to calibrate and evaluate the models of Kastiakov, Kastiakov modified, Philip, SCS, Novell, and Horton in different soil textures. To evaluate the acc...
متن کاملAnalytical Models for Soil Pore-Size Distribution After Tillage
for all properties whereas tillage practices contributed the most to the variation of infiltrability. Tillage causes soil fragmentation thereby increasing the proportion Quantifying the temporal dynamics of the PSD may of interaggregate (structural) pore space. The resulting tilled layer have important applications, but to do so in a determintends to be structurally unstable as manifested by a ...
متن کاملSelectivity of Particles through Rill Erosion in Different Soil Textures
Sediment selectivity during transport may provide basic information for evaluating on-site and off-site impacts of the soil erosion. Limited information is, however, available on the selectivity of sediments in rill erosion, particularly in the rainfed furrows. Toward this, the sediment selectivity was investigated in three soil textures (loam, loamy sand sand clay loam) under 10% slope using 9...
متن کاملLarge Trees to Different Amounts of Available Soil Water 1
Introduction A method was developed to manipulate avai lable so i l water on large trees by intercepting thrufal l with gutters placed under tree canopies and irrigating the intercepted thrufal l onto other trees . With this design, trees were exposed for 2 years to either 25 percent less thrufal l , normal thrufal l , or 25 percent addit ional thrufal l . Undercanopy construction in these plot...
متن کاملprediction of soil water retention curve using soil particle-size distribution
the soil water retention curve (swrc) is a basic characteristic of the determination of soil hydraulic properties, including unsaturated hydraulic conductivity. measurement of this curve is essential to research, thus scientists have focused on indirect methods such as pedotransfer functions and empirical relationships to estimate swrc easily. since there is a close relationship between swrc an...
